SUCTION-BOX.

Specification of Letters Patent.

Patented May 1W 191l.

Application filed August 7, 1909. Serial No. 511,777.

Be it known that we, Jo KING and JAMES NEARY, citizens of theUnitedStates, residing at the city of Kalamazoo, county of Kalamazoo, State ofMichigan, have invented certain new and useful Improvements inSuction-Boxes, of which the following is a specification.

This invention relates to improvements in suction rolls for paper makingmachines.

Our improved suction roll is particularly designed byus and we haveillustrated it adapted for use as a suction box although it may bereadily adapted and is desirable for use as a suction web forming rollfor paper making machines.

The main objects of our invention are to provide an improved suctionroll for paper,

making machines which can be readily adjusted to webs the desired width.

Further objects, and objects relatin to structural details willdefinitely appear f rom the detailed descri tion to follow.

We accomplish t e objects of our invention b the devices and meansdescribed in the f0 lowing specification.

The structure described constitutes one effective embodiment of ourinvention.

. Other embodiments would be readily devised by those skilled in theart;

The invention is clearly defined and pointed out in the claims.

AL structure constituting an effective and preferred embodiment of thefeatures of our invention is clearly illustrated in the accompanyingdrawing, forming a part of this specification, in which: 1

Fi re 1 is a detail view partially in lontwIiiial central section of astructure emodying the features of our invention. Fig. 2 is a detailvertical transverse section taken on a line corresponding to line 2-2 ofFig. 1, the frame being indicated partially by dotted lines. Fig. 3 is atransverse section taken on a line corresponding to line 3-3 of Fig. 1.Fig. 4 is an enlarged detailsection taken on a line corresponding toline 4-4 of Fig. 2, showing the suction connection. Fig. 5 is a detail.transverse section taken on-a line corresponding 'to line 5--5 of Fig.1, showin the arrangement of the head chambers an the adjusting screwstherefor. Fig. 6 is a detail longitudinal section of a modifiedconstruction in which the adjusting screws for the adjustable headsserve as the suction connection. Fig. 7 is a detail sect-ionof a furthermodification, the modification residing particularly in the suctionconnection, the shaft being provided with suctionpassages.

In the drawing, similar referencecharacters refer to similar partsthroughout the several views, and the sectional views are taken lookingin the direction of the little arrows at the ends of the section lines.

Referring to the drawing, 1 represents the standards upon which ourimproved suction roll is mounted. We have not illustrated our improvedsuction roll in connection with the other parts of a paper makingmachine as its adjustment in relation to the web carrying felt or beltwhen used as a suction box or in a suitable tank when used as a webforming roll will be readily understood by those skilled in the papermaking art. The shaft 2 is provided with suitable driving connectionsnot here illustrated.

Our improved suction roll comprises a body portlon having a plurality ofradially disposed compartments therein, each comartmentbeing providedwith a head chamiier at each end. The body portion of our improved rollpreferably comprises a central core 3 adapted to receive the shaft 2,the core being secured to the shaft by means of keys 4. The roll ispreferably made up of sections for convenience in construction. On thecores 3 are radially disposed partitions 5 which divide the roll into aplurality of compartments 6, the compartments being radially disposed asstated. At each end of each compartment is :1 Ion tudinally disposedpartition 7, forming in connection with the radial partitions 5 and theshell or outer wall 8, head chambers 9. In these head chambers are heads10; these heads are adjustablyarranged in the chambers, preferably bymounting the same upon the adjusting screws 11. The inner ends'oftheadjusting screws are in the structure illustrated, supported by thecross pieces 12 which connect and brace the longitudinal partitions 5.These cross pieces 12 being arranged in alinement form a substantiallychambers. the ends of the body being suitably formed to receive the ringportion as is illustrated in the drawing. The screws 11 are arrangedthrough these rings and are provided on their outer ends with toothedwheels 15 for the adjustment of the screws. To uniformly and quicklyadjust the; screws we preferably provide the adjusting racks 16 whichare pivoted to be shifted into and out of engaging position, the samewhen in engaging position being adapted to successively engage thewheels on the screws so that as the cylinder is revolved the screws areuniformly adjusted. A pair of these adjusting members are preferablyprovided at each end of the roll so that the heads may be adjusted in orout as occasion may require while the roll is re volved in the samedirection. At one end the fixed portion 13 of the end wall is providedwith openings 17, these openings are covered with a header plate 18.This header plate is provided with a header 19 to which the suction pipe20 is connected. As the roll revolves the compartments 5 aresuccessively connected with the header plate so that the suction issuccessively applied thereto. This header plate is preferably adjustablysupported by mounting upon the shaft and providing the same with a lug21 through which an adjusting screw 22 is arranged, the screw beingadapted to engage a fixed lug 230a the frame. The object of this is toadjust the header so that the compartment will be connected thereto atthe proper point in the revolution of the wheel. By providing theadjustable heads and the head chambers the roll can be quickly adjustedto the desired width of the web.

In the modified construction shown in Fig. 6 the adjusting screws 24 forthe heads are made tubular to serve as suction tubes, the header plate25 of the structure there illustrated being adapted to close the outerends of these suction tubes, the structure otherwise is substantiallythat of the preferred structure illustrated.

In the structure shown in Fig. 7, the shaft 26 is provided with suctionpassages 27 through which the connection is made to the suction 20, theheader 28 being arranged to embrace the outer end of the shaft asclearly appears in the drawing.

Our improved suction roll is simple in structure and it is veryeasy tomaintain the proper suction thereon. We, have illustrated and describedthe-same in detail in the form preferred by us on account of itsstructural simplicity and economy. We are, however, aware that it iscapable of considerable variation in structural details withoutdeparting from our invention, and we desire to be understood as claimingthe same in the specific form illustrated as well as broadly within thescope' of the appended claims.
